Installing win-10 in uefi mode on toshiba satellite-L50_a-1fm

Hi,
I would like to install windows 10 in uefi mode on this laptop. The problem is I can only boot from an usb-drive or DVD(instalation medium) in CSM mode and not in uefi mode.
But when I boot in CSM mode I can not install windows on a GPT parted drive.
any solutions for that ?

Try this with your Win10 media installed

Set the bios to UEFI mode and the boot device to be the internal HDD/SSD like normal.
Save and Exit.

During boot up, look for the message at the bottom of the screen that says something like Press XX to Select Boot Device. This is often F10, 11, or 12
When the window opens to select the boot device, Choose the one that matches your media but begins with "UEFI:"
(I've also seen a few times where it says UEFI: Windows... )
